Instruments to assess quality of life in people with mental health problems: a systematic review and dimension analysis of generic, domain- and disease-specific instruments.

OBJECTIVES: The importance of economic evaluations of mental healthcare interventions is increasingly recognized. Despite the multitude of available quality of life instruments, concerns have been raised regarding the content validity of these instruments, and hence suitability for use in mental health. The aim of this paper, therefore, was to assess the content validity and the suitability of existing quality of life instruments for use in economic evaluations in mental health problems. METHODS: In order to identify available quality of life instruments used in people with mental health problems, a systematic review was performed using the Embase, Medline and PsycINFO databases (time period January 2012 to January 2018). Two reviewers independently assessed study eligibility and executed data extraction. The evaluation framework of Connell and colleagues was used to assess whether the identified quality of life instruments cover the dimensions valued highly by people with mental health problems. Two reviewers independently mapped the content of each identified instrument onto the evaluation framework and indicated the extent to which the instrument covered each of the dimensions of the evaluation framework. RESULTS: Searches of databases yielded a total of 5727 references. Following duplicate removal and double-independent screening, 949 studies were included in the qualitative synthesis. A total of 44 unique quality of life instruments were identified, of which 12 were adapted versions of original instruments. The best coverage of the dimensions of the evaluation framework of Connell and colleagues was by the WHOQOL-100, S-QoL, SQLS, EDQoL, QLI and the IMHQOL, but none fully covered all dimensions of the evaluation framework. CONCLUSIONS: The results of this study highlight the multitude of available quality of life instruments used in people with mental health problems and indicate that none of the available quality of life instruments fully cover the dimensions previously found to be important in people with mental health problems. Future research should explore the possibilities of refining or expanding existing instruments as well as the development and testing of new quality of life instruments to ensure that all relevant quality of life dimensions for people with mental health problems are covered in evaluations.

Burden of illness of hip fractures in elderly Dutch patients.

Patients with hip fractures experience reduced health-related quality of life and have a reduced life expectancy. Patients' utilization of healthcare leads to costs to society. The results of the study can be used in future economic evaluations of treatments for hip fractures. PURPOSE: Hip fractures are associated with high mortality, reduced quality of life, and increased healthcare utilization, leading to an economic burden to society. The purpose of this study is to determine the burden of illness of hip fractures in elderly Dutch patients for specific time periods after surgery. METHODS: Patients with a hip fracture above the age of 65 were included in the study. In the 1-year period after surgery, patients were asked to complete a set of questionnaires pre-injury (retrospectively), and 1 week, 1 month, 3 months, 6 months and 12 months after surgery. The set of questionnaires included the Euroqol 5D (EQ-5D-3L), the iMTA Medical Consumption Questionnaire (iMCQ) and iMTA Productivity Cost Questionnaire (iPCQ). Health-related quality of life was calculated using Dutch tariffs. Costs were calculated using the methodology described in the Dutch costing manual. RESULTS: Approximately 20% of patients with a hip fracture died within 1 year. Health-related quality of life was significantly reduced compared to pre-injury values, and patients did not recover to their pre-injury values within 1 year. Total costs in the first year after injury were €27,573, of which 10% were due to costs of the procedure (€2706). Total follow-up costs (€24,876) were predominantly consisting of healthcare costs. Monthly costs decreased over time. CONCLUSIONS: Hip fractures lead to a burden to patients, resulting from mortality and health-related quality of life reductions, and to society, due to (healthcare) costs. The results of this study can be used in future economic evaluations.

Cost-effectiveness of multidimensional family therapy compared to cognitive behavioral therapy for adolescents with a cannabis use disorder: Data from a randomized controlled trial.

OBJECTIVE: To evaluate the cost-effectiveness of Multidimensional Family Therapy (MDFT) for adolescents with a cannabis use disorder, compared to Cognitive Behavioural Therapy (CBT). METHODS: A parallel-group randomized controlled trial was performed. 109 adolescents with a DSM-IV cannabis use disorder (CBT n=54; MDFT n=55) were included. Assessments were conducted at baseline, and 3, 6, 9 and 12 months post-baseline, and included measures on cannabis and other substance use, delinquency, health care utilization, and general health related quality of life. RESULTS: Excluding those with missing cost-data, 96 participants (MDFT n=49; CBT n=47) were included. From a health care perspective, the average annual direct medical costs in the CBT group were €2015 (95%C.I. 1397-2714), compared to €5446 (95%C.I. 4159-7092) in the MDFT group. The average quality-adjusted life years (QALY's) gained were 0.06 QALY higher for the MDFT group, which led to an incremental cost-effectiveness ratio (ICER) of 54,308 Euro/QALY or €43,405 per recovered patient. Taking the costs of delinquency into account, the costs increased to €21,330 (95%C.I. 12,389-32,894) for the CBT group and to €21,915 (95%C.I. 16,273-28,181) for the MDFT group, which lead to an ICER of 9266 Euro/QALY or a cost per recovered patient of €7491. CONCLUSIONS: This is the first comprehensive CEA of MDFT compared to CBT and it demonstrated that when costs of delinquency were included, the ICERS were modest. The results underline the importance of adopting a broader perspective regarding cost effectiveness analyses in mental health care.

[Cost-effectiveness in Dutch mental health care: future because of ROM?]. / Doelmatigheid in de ggz: toekomst dankzij ROM?

BACKGROUND: The document reporting Dutch mental health care negotiations for 2014-2017 calls for a cost decrease based on cost-effectiveness. Thanks to ROM, the Dutch mental health care seems well prepared for cost-effectiveness research. AIM: Evaluate how valid cost-effectiveness research should be established in mental health care and the role of rom therein. METHOD: Evaluation of requirements of cost-effectiveness research, trends, and a translation to Dutch mental health care. RESULTS: Valid cost-effectiveness research in mental health care requires the application of a societal perspective, a long time-horizon and an adequate evaluation of quality of life of patients. Healthcare consumption, outcome of care and characterisation of the patient population should be measured systematically and continuously. Currently, rom-data are not suitable to serve as a basis for cost-effectiveness research, although a proper basis is present. Further development of rom could lead to a situation in which mental health care is purchased on the basis of cost-effectiveness. However, cost-effectiveness will only really be improved if quality of care is rewarded, rather than rewarding activities that are not always related to outcome of care. CONCLUSION: Cost-effectiveness research in mental health care should focus on societal costs and benefits, quality of life and a long time-horizon. If developed further, rom has the potential to be a basis for cost-effectiveness research in the future.

[Can staging and profiling ensure that the costs of quality care are adequately reimbursed?]. / Vergoedingsaspecten: kunnen stagering en profilering ervoor zorgen dat de juiste zorg ook juist beloond wordt?

BACKGROUND: The current system for financing effective mental health can improve or reduce the quality of care provided. The system of financing includes reimbursing the care-provider, a risk-adjustment system for the health insurer and personal payments by the patient. Care-providers, patients and health insurers are worried that the current system is detrimental to quality care. AIM: To find out whether the financing system can be improved by the introduction of a system which weighs the costs according to the intensity of the care provided and which is based on staging and profiling. METHOD: We performed a critical evaluation of the current financing system and we explored how staging and profiling could help to keep complex care affordable. RESULTS: The current model for financing mental health care does not involve staging and profiling. Reimbursement is based on diagnoses and on the number of minutes of care provided, no differentiation being made between the levels of expertise required. As a result it can become financially unattractive to administer the best possible treatment to patients with the greatest needs. Staging and profiling have the potential to create the best possible relationship between the level of care needed by the patient and the treatment costs incurred, because the factors that led to the previous imbalance have been removed. CONCLUSION: Staging and profiling can be introduced gradually at roughly the same pace as the national system of risk-adjustment is being introduced for health insurers.

A microcosting study of diagnostic tests for the detection of coronary artery disease in The Netherlands.

OBJECTIVE: The primary aim of the present study was to calculate the actual costs of four diagnostic tests for the detection of coronary artery disease in the Netherlands using a microcosting methodology. As a secondary objective, the cost effectiveness of eight diagnostic strategies was examined, using microcosting and reimbursement fees subsequently as the cost estimate. DESIGN: A multicenter, retrospective cost analysis from a hospital perspective. SETTING: The study was conducted in three general hospitals in the Netherlands for 2006. INTERVENTIONS: Exercise electrocardiography (exECG), stress echocardiography (sECHO), single-photon emission computed tomography (SPECT) and coronary angiography (CA). RESULTS: The actual costs of exECG, sECHO, SPECT and CA were 33, 216, 614 and 1300 euro respectively. For all diagnostic tests, labour and indirect cost components (overheads and capital) together accounted for over 75% of the total costs. Consumables played a relatively important role in SPECT (14%). Hotel and nutrition were only applicable to SPECT and CA. Diagnostic services were solely performed for CA, but their costs were negligible (2%). Using microcosting estimates, exECG-sECHO-SPECT-CA was the most and CA the least cost effective strategy (397 and 1302 euro per accurately diagnosed patient). Using reimbursement fees, exECG-sECHO-CA was most and SPECT-CA least cost effective (147 and 567 euro per accurately diagnosed patient). CONCLUSIONS: The use of microcosting estimates instead of reimbursement fees led to different conclusions regarding the relative cost effectiveness of alternative strategies.

Comparing methodologies for the cost estimation of hospital services.

The aim of the study was to determine whether the total cost estimate of a hospital service remains reliable when the cost components of bottom-up microcosting were replaced by the cost components of top-down microcosting or gross costing. Total cost estimates were determined in representative general hospitals in the Netherlands for appendectomy, normal delivery, stroke and acute myocardial infarction for 2005. It was concluded that restricting the use of bottom-up microcosting to those cost components that have a great impact on the total costs (i.e., labour and inpatient stay) would likely result in reliable cost estimates.

Societal costs and quality of life of children suffering from attention deficient hyperactivity disorder (ADHD).

BACKGROUND: The impact of attention deficit hyperactive disorder (ADHD) in the Netherlands on health care utilisation, costs and quality of life of these children, as well as of their parents is unknown. OBJECTIVE: The aim of this study was to assess the direct medical costs of patients suffering from ADHD and their quality of life as well as the direct medical costs of their mothers. STUDY DESIGN: We selected a group of 70 children who were being treated by a paediatrician for ADHD based on the DSM-IV diagnostic criteria for ADHD. For comparison's sake, we also included a non-matched group of 35 children with behaviour problems and 60 children with no behaviour problem from a large school population-based study on the detection of ADHD. We collected information on the health care utilisation of the children applying the Trimbos and iMTA questionnaire on Costs associated with Psychiatric illness' (TiC-P). Their health related quality of life was collected by using the Dutch 50-item parent version of the Child Health Questionnaire (CHQ PF-50). Measurements were at baseline and at 6 months. Subsequently, we collected data on the health utilisation of the mothers and their production losses due to absence from work and reduced efficiency. RESULTS: The mean direct medical costs per ADHD patient per year were euro 2040 or euro 1173 when leaving out one patient with a long-term hospital admission, compared to euro 288 for the group of children with behaviour problems and euro 177 for the group of children with no behaviour problems. The direct medical costs for children who had psychiatric co-morbidities were significantly higher compared to children with ADHD alone. The mean medical costs per year for the mothers of the ADHD patients were significantly higher than for the mothers of the children with behaviour problems and the mothers of children with no behaviour problems respectively euro 728, euro 202 and euro 154. The physical summary score showed no significant differences between the groups. However, the score on the Psychosocial Summary Score dimension was significantly lower for ADHD patients compared to the scores of the children in the two other samples. The mean annual indirect costs due to absence from work and reduced efficiency at work were euro 2243 for the mothers of the ADHD patients compared to euro 408 for the mothers of children with behaviour problems and euro 674 for the mothers of children with no behaviour problems. CONCLUSION: Our study showed that the direct medical costs of ADHD patients were relatively high. Additionally, our study indicated that ADHD appears to be accompanied by higher (mental) health care costs for the mothers of ADHD patients and by increased indirect costs for this group.

Influence of waiting time on cost-effectiveness.

Economic evaluations of health care programs are intended to support policy decisions and therefore should incorporate elements of the health care environment such as waiting lists. We explore possible relationships between waiting time and the cost-effectiveness of health care programs. The impact of waiting on cost-effectiveness is very scenario dependent and may be substantial, especially if health loss while waiting is partly or completely non-reversible. We argue that economic evaluations of health care programs in countries with waiting lists should consider the possible impact of waiting on costs and health effects.

The societal costs and quality of life of patients suffering from bipolar disorder in the Netherlands.

OBJECTIVE: To assess the societal costs and quality of life of patients suffering from bipolar disorder in the Netherlands. METHOD: Forty persons with a lifetime diagnosis of bipolar disorder (SCID/DSM-IV) and representative for the Dutch general population were interviewed to collect data on direct (use of medical resources) and indirect (productivity losses because of absence from work and reduced efficiency at work) costs of illness. Respondents' quality of life was also assessed. Prevalence (5.2%) of bipolar disorder was used to estimate total costs. RESULTS: Total costs of bipolar disorder were estimated at US 1.83 billion dollars (total direct costs = US 454 million dollars; total indirect costs = US 1.37 billion dollars). Participants' quality-of-life scores were lower than those of the general population. CONCLUSION: The societal costs form patients suffering of bipolar disorder in the Netherlands were high, especially the indirect costs because of absence from work. The quality of life of bipolar patients was lower than the general population.

The cost effectiveness of tapered versus abrupt discontinuation of oral cyclosporin microemulsion for the treatment of psoriasis.

OBJECTIVE: To assess the cost effectiveness of tapered versus abrupt discontinuation of a microemulsion formulation of cyclosporin in patients with chronic plaque psoriasis. METHODS: A cost-effectiveness analysis was performed in parallel with a non-blind, multicentre, international clinical trial of the safety and efficacy of intermittent short courses of cyclosporin. Direct and indirect costs were considered within a 1-year period following randomisation. PATIENTS: Patients with chronic plaque psoriasis inadequately controlled with topical treatment. STUDY PERSPECTIVE: The study was conducted from a societal perspective and was performed using data from Canada, Spain, Turkey and the UK. MAIN OUTCOMES MEASURES: The health outcome used was the total number of systemic therapy-free days (STFDs) over the first year. The mean incremental cost-effectiveness ratio (ICER) was determined by dividing the differences in average cost per patient by the differences in average STFDs per patient. RESULTS: The overall ICER was dominant because tapered discontinuation was associated with both lower costs and improved efficacy in comparison with abrupt discontinuation. Further analyses showed that tapered discontinuation was a cost-effective alternative to abrupt discontinuation therapy, even when a conservative definition for cost effectiveness was adopted. CONCLUSION: This cost-effectiveness analysis demonstrated that tapering cyclosporin was more cost effective than abruptly stopping cyclosporin in patients with chronic plaque psoriasis.

Cost of illness in adult patients with hypopituitarism.

OBJECTIVE: To compare the healthcare costs of patients with hypopituitarism with those of individuals from the general population. DESIGN: A retrospective study of costs over 1 year. Estimates of direct and indirect health-related costs were calculated for patients from the general population using existing databases, and for patients with hypopituitarism using records of all patients eligible to participate on 31 December 1989 who could be traced, were willing to participate and had not been treated for acromegaly or Cushing's disease. SETTING: The catchment area of the Endocrine Unit, Sahlgrenska Hospital, Gothenburg. The study was conducted from the societal perspective. Reference data were collected from official regional and national registries. PATIENTS: 199 patients with adult-onset hypopituitarism in whom replacement therapy was given to maintain the adrenal, thyroid and gonadal (but not the somatotropic) axes. MAIN OUTCOME MEASURES AND RESULTS: Direct and indirect costs incurred by patients with hypopituitarism were higher than those incurred by individuals from the general population. The total direct costs per patient were Swedish Crowns (SEK)22,920 vs SEK12,080 (p < 0.003) in the general population, and the highest costs were related to inpatient care. Of the patients aged 16 to 64 years, 22% had drawn a disability pension versus the expected 11.3% (p < 0.003) in the general population, and the patients had a mean sick leave of 38.4 days vs 23.5 (p < 0.001). Total excess costs for all patients with hypopituitarism were SEK 35,768 per patient (p < 0.007). CONCLUSIONS: Patients with hypopituitarism incur more health-related costs than individuals from the general population. They also take more sick leave days and are more likely to claim a disability pension than members of the general population. Further cost analyses are needed to determine whether improvements in diagnostic and surgical procedures, and hormone replacement therapy, can reduce the healthcare costs of patients with hypopituitarism.

The burden of illness of hypopituitary adults with growth hormone deficiency.

OBJECTIVE: The negative metabolic and psychosocial consequences of growth hormone deficiency (GHD) in adults are now well established. In the present study, an attempt was made to quantify the burden of illness, in terms of lost productivity and increased medical consumption, associated with hypopituitarism and untreated GHD. DESIGN AND SETTING: The study population consisted of 129 Belgian adults with untreated GHD associated with hypopituitarism after pituitary surgery. The Short-Form 36 Health Survey (SF-36) was used to assess health status, and the Health and Labour Questionnaire was used to measure production losses and labour performance. Data on medical consumption were also collected. MAIN OUTCOME MEASURES AND RESULTS: Hypopituitary patients reported a lower health status than that of the general population in all but two dimensions of the SF-36 (pain and physical functioning). Nearly 11% of the patients reported being incapacitated for paid employment due to health problems, compared with 4.8% of the general Belgian population. Patients in paid employment reported a mean of 19.8 days of sickness leave per year, which is twice that in the general population. The annual number of visits to general practitioners and specialists was also higher in the patients (9.6 and 6.5 visits, respectively, for the patients compared with corresponding figures of 2.1 and 1.5 for the general Belgian population). The average annual number of days spent in hospital was 3.5 for the patients compared with 2.3 in the general population. The annual healthcare costs and costs due to production losses calculated for hypopituitary patients who had received pituitary surgery amounted to 135,024 Belgian francs (BeF) or $US4340 (1995 values). This compares with the mean annual cost per person for the Belgian population as a whole of BeF68,569 or $US2204. CONCLUSIONS: Hypopituitary patients with untreated GHD therefore have a higher cost to society in terms of lost production and medical consumption than the average Belgian population.
